摘　　要：通过数据分析发现,机车车辆用整体式橡胶关节径向刚度(有套筒工装)与轴向刚度(无套筒工装)之间和有/无套筒工装的径向刚度之间具有线性相关性,通过回归分析获得整体式橡胶关节径向刚度与轴向刚度之间和有/无套筒工装径向刚度之间的回归方程。径向预压式橡胶关节及轴向预压式橡胶关节径向刚度与压装刚度也具有线性相关性,可通过回归方程以橡胶关节压装刚度计算其径向刚度。本回归分析方法可以提高橡胶关节径向刚度的检测效率,拟合偏差在±5%以内。Through data analysis,it was found that there were linear correlations between the radial stiffness(with sleeve tooling)and the axial stiffness(without sleeve tooling)of the integral rubber joint for rolling stock,and between the radial stiffness with sleeve tooling and the radial stiffness without sleeve tooling of the integral rubber joint.Through regression analysis,the regression equations between the radial stiffness and the axial stiffness of the integral rubber joint,and the radial stiffness(with sleeve tooling)and the radial stiffness(without sleeve tooling)of the integral rubber joint were obtained.The radial stiffness and press fitting stiffness of the radial preloaded rubber joint and axial preloaded rubber joint were also linearly related,and the radial stiffness of the rubber joint could be calculated by the press fitting stiffness through the regression equations.This regression analysis method could improve the measuring efficiency of the radial stiffness of the rubber joint,and the fitting deviation was within±5%.
